Description

Technical Field

[0001] The utility model relates to the field of electric wires, in particular to a central control electric wire used in new energy electric vehicles. Background Art

[0002] With the development of the automobile industry, the use of new energy electric vehicles is becoming more and more common. However, compared with traditional gasoline-driven vehicles, new energy electric vehicles need to rely on the central control system to control the electric vehicle, and the central control system needs to transmit corresponding electrical signals to each module of the electric vehicle through wires in order to achieve the purpose of controlling the electric vehicle.

[0003] However, if the wires burn during the process of transmitting electrical signals, it is very easy to cause the central control system to fail to transmit electrical signals, thereby losing the ability to control the tram and causing serious accidents. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a high-voltage central control wire used in new energy electric vehicles, which can ensure that the electric wire remains in a usable state for a certain period of time when the electric wire burns, thereby preventing the electric vehicle from losing control.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a central control wire applied to new energy electric vehicles, including a main body, the main body including two conductors, the outer layer of each conductor is wrapped with a rubber insulating layer, the outer layers of the two conductors are simultaneously coated with a semi-conductive wrapping layer and wrapped into a cylindrical shape, the semi-conductive wrapping layer and the rubber insulating layer are filled with ceramic rubber, and a flame retardant layer is provided between the two conductors.

[0006] Compared with the prior art, the advantages of the utility model are: through the design of two conductors, the stability of the electric signal transmission of the wire can be increased, and when one conductor is damaged, the other conductor can still transmit the electric signal; the design of the rubber insulation layer can avoid the interference of the electric signal between the two wires; the design of the ceramic rubber filling can play a flame retardant effect, which can not only avoid the influence of the external combustion environment on the conductor, but also avoid the combustion influence between the two conductors, thereby ensuring that the wire can maintain its usability for a long time in the combustion environment; the design of the semi-conductive wrapping layer can play a preliminary shielding effect, and at the same time, its cylindrical structure can shape the structure of the wire, making the wire not easy to be damaged and having better stability in use; the design of the flame retardant layer is to ensure the combustion interval design between the two conductors, so as to avoid the two conductors being close to each other when the wire is extruded and formed, causing the combustion to spread rapidly between the two conductors.

[0007] As an improvement of the present invention, the flame retardant layer is made of flame retardant polypropylene material. Through the improvement, the material difference between the flame retardant layer and the ceramic rubber filling is utilized, and both materials have flame retardancy. During the combustion propagation process, a stage change of cross-material combustion will be formed, thereby making the combustion propagation time between the conductors longer.

[0008] As an improvement of the utility model, the flame retardant layer is arranged perpendicular to the central connecting line of the two conductors, and the two ends of the flame retardant layer are respectively against the semi-conductive wrapping layer. Through the improvement, the isolation between the ceramic rubber fillings in the areas where the two conductors are located is guaranteed, and rapid spreading between the ceramic rubber fillings in the two areas is avoided, so that the role of the flame retardant layer can be fully exerted.

[0009] As an improvement of the present invention, the outer layer of the semi-conductive winding layer is wrapped with a double shielding layer, and the double shielding layer includes a copper wire shielding layer and two copper tape shielding layers, and the copper wire shielding layer is arranged between the two copper tape shielding layers. Through the improvement, the design of the double shielding layer can fully guarantee the shielding effect of the wire, avoid being affected by the electromagnetic field of the external environment, and will not affect the external environment. The design of the copper wire shielding layer can enhance the strength of the double shielding layer, and the design of the two copper tape shielding layers can ensure the integrity of the shielding area and avoid shielding loopholes.

[0010] As an improvement of the utility model, the outermost layer of the main body is provided with an outer sheath, and the outer sheath is made of low-smoke halogen-free material. Through the improvement, the outer sheath plays a role in protecting the wires, and the outer sheath is made of low-smoke halogen-free material to avoid the formation of toxic gases containing halogen elements when the wires burn, causing poisoning of people on the tram.

[0013] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0014] like Figure 1As shown, a central control wire used in new energy electric vehicles includes a main body, which includes two conductors 1. The outer layer of each conductor 1 is wrapped with a rubber insulating layer 2. The outer layers of the two conductors 1 are simultaneously coated with a semi-conductive wrapping layer 3 and wrapped into a cylindrical shape. A ceramic rubber filling 4 is passed between the semi-conductive wrapping layer 3 and the rubber insulating layer 2. A flame retardant layer 5 is provided between the two conductors 1. The flame retardant layer 5 is made of flame retardant polypropylene material. The flame retardant layer 5 is arranged perpendicular to the central connecting line of the two conductors 1, and the two ends of the flame retardant layer 5 are respectively against the semi-conductive wrapping layer 3.

[0015] The outer layer of the semi-conductive wrapping layer 3 is wrapped with a double shielding layer 6, and the double shielding layer 6 includes a copper wire shielding layer 6.1 and two copper tape shielding layers 6.2. The copper wire shielding layer 6.1 is arranged between the two copper tape shielding layers 6.2.

[0016] The outermost layer of the body is provided with an outer sheath 7, and the outer sheath 7 is made of low-smoke halogen-free material.

[0017] The semi-conductive wrapping layer 3 is formed by wrapping with a semi-conductive nylon tape.

[0018] When a high-voltage central control wire used in a new energy electric vehicle burns in the external environment, the gas formed by the combustion of the outer sheath 7 will not cause poisoning reactions to the people on the vehicle, so that the people on the vehicle can still take corresponding emergency measures to solve the burning phenomenon or leave the scene. When the burning phenomenon spreads to the inner circle of the wire, the design of the ceramic rubber filling 4 and the flame retardant layer 5 can fully delay the time when both conductors 1 are damaged, so as to ensure that the people on the vehicle can still control the electric vehicle through the central control system, stop the vehicle on the roadside and open the door to escape in time, avoiding the burning phenomenon from causing a bigger accident. Similarly, when the conductor 1 inside the wire breaks down due to quality problems or spontaneous combustion caused by the external environment temperature, the probability of the two conductors 1 being burned and damaged at the same time is low, and the conductor 1 that can still maintain a working state at this time will not be spread by the burning in a short time because it is protected by the ceramic rubber filling 4 and the flame retardant layer 5, so that the people on the vehicle can still control the electric vehicle to stop on the roadside and open the door to escape in time, avoiding the burning phenomenon from causing a bigger accident. The use status of the conductor 1 only requires corresponding electrical connection monitoring. When the conductor 1 is damaged, a timely alarm is issued to prompt the personnel on the vehicle to take corresponding emergency measures. This connection monitoring is a conventional technical means.

[0019] The above description is only for the best embodiment of the utility model, but it cannot be understood as a limitation of the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. All changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
